I do not think it should be that way. Business can start anytime, whether after or before rich. Many people are already rich, but still doing business. They have a lot of capital, and many of them are also successful.
Business can be done by anyone, anytime and anywhere. The rich or not the rich have equal opportunities to succeed in business. The success of the business is determined by the individual's ability. The rich may be easier because of a lot of capital. That's what sets it apart from the poor. But if we have a good network, we can also get capital or loan.
